PAP ER-PERFORATOR.

SPECIFICATION forming part of Letters Patent No. 736,614, dated August 18, 1903.

Application filed May 13, 1908. Serial No. 156,863. (No model.)

To all whom it may concern:

Be it known that I, WALTER S. MENDEN- HALL, a citizen of the United States, residing at Norwood, in the county of Hamilton and State of Ohio, have invented certain new and usefullmprovements in Paper-Perforators, of which the following is a specification.

My invention relates to a new and improved hand-operated paper-perforator.

The object is to provide a simple, convenient, and cheap construction with the least possible number of operative points.

The features of the invention are more fully set forth in the description of the accompanying drawings, making a part of this specification, in which Figure l is a front elevation of my device, partly in section. Fig. 2 is a side elevation. Fig. 3 is a section on line 00 00, Fig. 1.

A represents the base. B B represent the upright sleeves thereon, within which the punch members D D reciprocate.

0 represents the female members under the punches D D.

E represents a cross-bar connecting and carrying the tops of the punches D D. Between the top ends of the sleeves B B and under the surface of the cross-bar E at each end are the coil-springs b 1) around the punches D D.

a a represent the slits in the front sides of the sleeves B B for the insertion of the paper to be perforated.

F represents a bolt suspended from the bar E between the sleeves B B, having the headed lower end 0.

G represents a stop secured to the baseplate by bolt f between sleeves B B, said stop having the forwardly-extending finger cl, bifurcated at its end under the cross-bar and engaging bolt F above the head 0. Obviously this stop is secured in position after the other members are assembled.

The punches are supported in the ends of bar E by means of heads g g. The coilsprings press upwardly the cross-bar and its punches, holding them in position shown in Fig. 1 as limited by the engaging positions of the bolt and stop.

Having described my invention, I claim- 1. In a paper-perforator, a base, two upwardly projecting sleeves, female punch members, transverse slits in the sleeves for presentation of paper, a cross-bar, punches in the ends thereof, fitting within said sleeves, a headed bolt suspended from the cross-bar, a stop secured to the base under the crossbar engaging the bolt above the head, and springs around the punches between the tops of the sleeve and the bottom of the cross-bar, holding in normal engagement the stop and headed bolt, substantially as described.

2. In a paper-perforator, a base, two upwardly projecting sleeves having female punch members and transverse slits for the paper, a cross-bar, punches in the ends thereof, seating in said sleeves, springs around the punches between the tops of the sleeves and cross-bar exerting a lifting tension on the punches, and stop devices suspended from the cross-bar and supported on the base between the sleeves, adapted to limit the springactuated rise of the punches, substantially as described.

In testimony whereof I have hereunto set my hand.

WALTER S. MENDENI-IALL.
